Transform 变换

Transform 变换

Inherits from Component,IEnumerable

Position, rotation and scale of an object.

物体的位置、旋转和缩放。

Every object in a scene has a Transform.  It's used to store and manipulate the position, rotation and scale of   the object.  Every Transform can have a parent, which allows you to apply position,   rotation and scale hierarchically. This is the hierarchy seen in the   Hierarchy pane.  They also support enumerators so you can loop through children using:

场景中的每一个物体都有一个Transform。用于储存并操控物体的位置、旋转和缩放。每一个Transform可以有一个父级，允许你分层次应用位置、旋转和缩放。可以在Hierarchy面板查看层次关系。他们也支持计数器（enumerator），因此你可以使用循环遍历子物体。

using UnityEngine;using System.Collections;public class example : MonoBehaviour {public void Awake() {foreach (Transform child in transform) {child.position += Vector3.up * 10.0F;}}}

// Moves all transform children 10 units upwards!//向上移动所有变换的子物体10个单位for (var child : Transform in transform) {child.position += Vector3.up * 10.0;}
